Entire City Disappeared Under Volcanic Mud Overnight in 1985

Описание: Entire City Disappeared Under Volcanic Mud Overnight in 1985

On November 13, 1985, the city of Armero in Colombia completely vanished under volcanic mud in just 15 minutes. This video explores the tragic story of Nevado del Ruiz volcano eruption that buried an entire Colombian city under a devastating lahar (volcanic mudflow). Despite clear warnings from scientists and volcanic risk maps delivered to authorities just one month before, the evacuation was never ordered. The result was one of the deadliest volcanic disasters of the 20th century, with over 25,000 people lost when the pyroclastic flows melted the glacier, creating a massive mudflow that traveled at 50 km/h down the mountain. Learn about the science behind lahars, why this disaster was completely preventable, and how the tragedy of Armero revolutionized global volcanic monitoring systems. This documentary examines the geological processes of stratovolcanoes, the Pacific Ring of Fire, and the critical importance of heeding scientific warnings during volcanic emergencies. Discover how volcanic mudflows form, their devastating speed and power, and why they remain one of the most dangerous secondary hazards of volcanic eruptions. The story includes the heartbreaking case of Omayra Sánchez and explores how modern volcanic monitoring has evolved since this catastrophic event. Understanding volcanic hazards, lahar formation, pyroclastic flows, and emergency evacuation procedures can save lives.
